Since these Rams have that thick top to the tailgate, I imagine most canopies have the curved plastic at the bottom of the rear window that seals up against the tailgate. Mine has a pretty nice seal everywhere but even after just a few days, I notice it is starting to scuff the paint at the top of the tailgate right underneath where the plastic ends on the tailgate. I was thinking of putting something like a 1/16' thick weather stripping at the underside of the curved plastic part of the canopy door to provide a little cushion between the two but wanted to see if you guys had a better idea.
